The present invention provides electronic communication devices, methods of forming electrical communication devices, and communications methods. An electronic communication device adapted to receive electronic signals includes: a housing comprising a substrate and an encapsulant; an integrated circuit provided within the housing and comprising transponder circuitry operable to communicate an identification signal responsive to receiving a polling signal; an antenna provided within the housing and being coupled with the transponder circuitry; and a ground plane provided within the housing and being spaced from the antenna and configured to shield some of the electronic signals from the antenna and reflect others of the electronic signals towards the antenna. A method of forming an electronic signal communication device includes providing a substrate having a support surface; providing a conductive layer adjacent at least a portion of the support surface; providing a dielectric layer over the conductive layer; providing an antenna over the dielectric layer; coupling an integrated circuit with the antenna; and encapsulating the antenna, the dielectric layer, and the integrated circuit using a flowable encapsulant.
Abstract:
Microelectronic imaging units and methods for manufacturing a plurality of imaging units at the wafer level are disclosed herein. In one embodiment, a method for manufacturing a plurality of imaging units includes providing an imager workpiece having a plurality of imaging dies including integrated circuits, external contacts electrically coupled to the integrated circuits, and image sensors operably coupled to the integrated circuits. The individual image sensors include at least one dark current pixel at a perimeter portion of the image sensor. The method includes depositing a cover layer onto the workpiece and over the image sensors. The method further includes patterning and selectively developing the cover layer to form discrete volumes of cover layer material over corresponding image sensors. The discrete volumes of cover layer material have sidewalls aligned with an inboard edge of the individual dark current pixels such that the dark current pixels are not covered by the discrete volumes.
Abstract:
Computer method and apparatus for collaborative web search operate in an intranet with non-existent or defective link structure. A search engine produces an initial search result list in response to a user query. A list optimizer reranks pages on the initial list based on implicit user recommendation or endorsement of pages. A last click heuristic defines user endorsement of a page. To form the final result list, the list optimizer scores each page according to reranking, a textual match (or information retrieval score) of the page with the query and an adjustment value.
Abstract:
An integrated circuit structure is formed using a damascene process that involves forming a trench or cavity for the structure in a temporary layer of material. A conductive material, such as copper, can then be deposited on the temporary layer to overfill the trench or cavity, and the excess conductive material can be removed by polishing down to the surface of the temporary layer. The integrated circuit structure can then be exposed by removing the temporary layer. One example of an integrated circuit structure that can be formed using this method is an upper electrode in an MRAM array. By using the process to form an upper electrode in an MRAM array, the process of forming a magnetic keeper around the upper electrode is advantageously simplified.

Abstract:
Microelectronic workpieces that have bump sites over bond-pads and methods of fabricating such bump sites. One embodiment of such a workpiece, for example, includes a substrate having a plurality of microelectronic dies comprising integrated circuitry and bond-pads, such as copper bond-pads, electrically coupled to the integrated circuitry. The workpiece further includes (a) a dielectric structure having a plurality of openings with sidewalls projecting from corresponding bond-pads, and (b) a plurality of caps over corresponding bond-pads. The individual caps can include a discrete portion of a barrier layer attached to the bond-pads and the sidewalls of the openings, and a discrete portion of a cap layer on the barrier layer. The caps are electrically isolated from each other and self-aligned with corresponding bond-pads without forming a mask layer over the cap layer.
